BCX plywood consists of three layers. “B” stands for the B-grade face, which is a smooth and sanded surface suitable for finishing. The “C” represents the C-grade back, which may have some imperfections but is still structurally sound. The “X” signifies that it is exterior-grade plywood, designed to withstand outdoor conditions.

Grading in BCX Plywood
B-Grade Plywood
B-grade plywood is known for its smooth surface with few knots or other visual imperfections. This makes it a preferred choice for projects where appearance plays an important role, such as crafting fine cabinetry or creating elegant furniture. The B-grade face gives an attractive finish which enhances their overall appeal.
C-Grade Plywood
C-grade plywood may have small knots, patches, or other blemishes on the face veneer. These imperfections do not compromise the structural integrity of the wood. C-grade plywood is often selected for construction projects where aesthetics take a backseat to functionality and cost-effectiveness.
X-Grade Plywood
X-grade plywood is suitable for exposure to the elements. This type of plywood is crafted to withstand moisture, humidity, and temperature variations without significant warping or deterioration. It is a reliable choice for outdoor projects like building decks, fences, or roofing structures where durability and weather resistance are paramount.
When Should BCX plywood be used
BCX plywood is a common choice for construction and framing projects, providing both structural support and a clean finish. It’s also used for exterior and interior sheathing, offering strength and insulation. A range of DIY projects, from building shelves to crafting custom cabinets, can make use of BCX. We would recommend you use BCX on a project where one side is going to be exposed and needs to look good. Like wall linings in your garage.
Advantages of BCX Plywood
BCX Plywood is known for its strength and durability, making it great for construction. You can use it indoors or outdoors, giving you flexibility for different projects. It’s also budget-friendly compared to higher-grade plywood, while its smooth surface makes it easy to paint or stain for a polished finish.
Disadvantages of BCX Plywood
BCX Plywood may have knots or blemishes on its surface, making it less suitable for fine woodworking or furniture making. BCX plywood also requires proper sealing or treatment to improve moisture resistance, especially for outdoor use. Its weight can be a concern for larger projects, potentially needing further structural support.
Special Considerations
Tips for cutting, fastening, and finishing
Use sharp saw blades when cutting to minimize splintering. Use appropriate screws or nails such as galvanized or stainless steel screws, and ensure they’re evenly spaced. When finishing, sand the surface for a smooth result and consider priming before painting or staining for the best look.
